Hello!
I am building an audio recording system with an ESP32 and external adc (PCM1865)
To start the data reading, I use:
i2s_read(I2S_NUM, user_given_buffer[cnt], user_given_buffer_size, &i2s_bytes_read, 100);
My question is, what is "&i2s_bytes_read" ? And how to use it?
Thank you

Can ESP32 receive analog studio microphone input?
Hello, I want to make a device that can receive input from a high quality microphone (TRS cable). Can ESP32 do this? Here is an example of a microphone I would like to use https://www.bhphotovideo.com/c/product/1012003-REG/rode_videomic_go_videomic_go_on_camera_shotgun.html?ap=y&smp=y&srsltid=AWLEVJ...
